Has their been anything like a fluorescent bulb that whenever one of the metal tips is struck, lightning strikes the object that was touched? I also had the idea of a person who cannot touch any liquid. When he is submerged he is surrounded by a force-field of unknown origin and makeup. also when he tries to take a drink, the liquid evaporates before it can get to his mouth.

There is a rubber duck with liquid repulsion. It causes water to sort-of cease to be in a certain volume of space around it. The water comes back like nothing happened when the duck is moved.

The lightbulb, I don't think I've seen anything like it before. I'm also not sold that it's a good concept. Seems a bit too much like a D&D item to stick around here. Replace "flourescent bulb" with "stick" and you've got a Wand of Lightning Bolt.

What if it was a capsule that simply resembled a fluorescent bulb, and when introduced to electricity, it released a being who appeared to be some sort of sentient gaseous cloud and could strike with powerful arcs of electricity from afar?
